I am a bit perplexed at this. Where ever would he have heard this term?
"A garden of rocks or a garden of plants?"
"Rocks and plants," he replies without any hesitation.
"I have an area I do not like. We could make one there." I caution, "We can't start until after I get done with summer school next week and we would have to collect some rocks from the farm."
"Can't we start now?" he asks like any avid gardener with a project.
At seven, he knows what sort of garden he would like to try. He has already had quite a bit of experience with flower and vegetable gardens.
I have been mulling it over and tweaking with this plant and that, but without further consideration, a rock garden it will be.
